Answer:
There are many important qualities needed to be successful.
Step-by-step explanation:
In order for a paragraph to have unity or coherence, it is important that all the sentences in it be related to the topic sentence or provide more specific information about the topic sentence. In the paragraph, the sentence “Personal initiative is one of life's greatest freebies” is the topic sentence (it summarizes the main idea of the paragraph). Most sentences add up to that main idea by describing what it means personal initiative, by laying out the benefits of having it, etc. But the sentence “There are many important qualities needed to be successful” is off-topic: it does not say anything that can be related to personal initiative.
